the command you are looking for is: atm ilmi-pvc-discovery
this command is also helpful if you are told to setup a pvc on a
subinterface w/o putting any pvc commands on the interface (see bootcamp
lab; the command also requires the optional keyword 'subinterface')
Another comment on ilmi: This is the mechanism that is used to register
YOUR address with the ATM switch. The UNI client (ie. the router interface)
takes the 13 octet switch prefix it learns via ilmi and appends its own ESI
(6 octets) and SEL (1 octet) to create a full 20-octet NSAP that it sends
back to the switch via ilmi. This is how the ATM switch knows which
addresses are connected to it so that it can perform dynamic connection
setup (ie. assign the appropriate VPI/VCI) based on the called NSAP. Once
address registration is complete, you technically don't need ilmi anymore.
However, if the ATM switch hiccups and loses the address registration
(simulate with a shut/no shut on the LS1010), then the CLIP won't work b/c
the LS1010 won't know the NSAP of the connected port.
